SEAT-CUSHION STRUCTURE.

Specification of Letters Patent.

Patented May 18, 1915 Application filed February 26, 1914. Serial No.$211,152.

within the structure and secured thereinquickly and easily with aminimum of hand work.

The invention comprises a structure which is provided with'an auxiliarybottom frame formed in two sections which 'can be quickly and easilysecured together so that the parts of the cushion structure'can be sewedto the auxiliary frame on a machine before the sections of the frame arejoined together.

It further consists of a construction in which the cushion structureproper can be joined together and the springs placed with- 1n the sameand secured thereby by a single operation. I

Further objects, and objects relating to details and economies ofconstruction will definitely appear'from the detailed -descrip-.

tion to follow.

I accomplish the objects of my invention by the devices and meansdescribed in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure constituting a prefer-redembodiment of my invention is shownin the accompanying drawing forming a part of this specification, inwhich:

' Figure I is a perspective view of a structure embodying my invention.Fig. II is a perspective .view of said structure, the bottom being shownuppermost and a portion of the bottom being. broken away to show the setof springs secured in place. Fig. III is a perspective view showing thestructure with the sides turned down in position to secure them to thesections of the auxiliary frame. The sections of said frame are showndetached from each other. Fig. IV is a perspective view showing thestructure ready to receive the springs and with the bottom thrown back.Fig. V is an enlarged detail fragmentary view of a corner of thestructure showing the manner of j oining the two sections of theauxiliary frame together. FigHVI is an enlarged detail sectional View onthe line 66 of Fig. I, showing the method iliary frame,

the bottom frame, and the border wire of the springs.

Fig. v11 is a of securing together the auxbottom plan view of a modifiedform of my invention showing the manner of securing the springs in placein the seat structure. Fig. VIII is a detail sectional view on the line88 of Fig. VII, showing the manner of securing the sections of theauxiliary frame together.

In the drawing, similar reference characters refer to similar partsthroughout the several views and the sectional views are taken lookingin the direction of the little arrowsat the ends of the section lines.

' Considering the numbered parts of the drawing, lis the padded portionof the seat and 2 is a side strip which-is stitched or suitably securedto the padded portion, as atthe auxiliary frame are secured together;

The U-shaped section is disposed at the bottom of the side strip 2 andthe side strip is folded over said U-shaped frame and stitched as at 5.The padded portion is also provided with the section 6 which is securedthereto at the front thereof and is folded over, the cross bar sectionof the auxiliary frame and stitched as at 8.

At the ends of the section 6. are provided the triangular pieces 9, 9which overlap the adjacent ends of the side strip 2 when the seatstructure is assembled. These triangular'sections 9, 9 are provided witheyelets 10, 10 which aline with the eyelets 11, 11 provided in the sidestrip 2 and a clench button or suitable fastener 12 .is passed throughthe same so as to connect the triangular sections and the side strip andthus secure the sideportions of the seat structure together. It will beseen that when the side portions are thus secured, the right angleportions 7,

within the hollow ends of the U-shaped frame member 4. i

13 represents a set of springs of any approved construction which isdisposed within the recess or chamber formed by the padded portion and.the side wall portions. Said set of springs has a border wire 13 aroundthe edge thereof.

A bottom 14 is provided which has at its edge the wire frame 15. Thesprings are placed within the recess or chamber and the bottom is placedover them. The bottom is 'then fastened to the seat structure proper bymeans of the split ring fasteners 17 which embrace the auxiliary bottomframe, the bottom frame 15 and the border wire 13'. The-split ringfasteners 17 serve to hold the bottom 14, springs 13, and the auxiliarybottom frame securely in position, and these fasteners 17 can veryreadily be clamped into place.

Ventilating openings 16 are provided in the bottom to permit of theescape of' air from the interior of the cushion.

In Fig. VII I have shown a modification inwhich the bottom 14 is omittedand the springs are connected to the two part auxiliary bottom frame bymeans of the split ring fasteners 17. In this structure I connect theends 77 of the cross bar section and the ends of the U-shaped section 4of the auxiliary frame by means .of a coupling 18 provided with rightand left hand screw threads engaging the threaded ends of said members.I may also use a ferrule ofany kind.

From the description of the parts given above, the method ofconstructing this cushion can be very readily understood. Fig. III showsthe structure with the parts of the auxiliary frame detached from eachother and the seat turned wrong side out. In this position the sidestrip 2 can be sewed to the top 1 and the seam 5 can be stitched in thebottom edgeof the strip 2, on a machine; The front strip 6 can also beattached to the top and the seam 8 stitched thereinto secure the crossbar section. The structure is then turned right side out by turning theside strip 2 upwardly. the sections of the auxiliary frame are fastenedtogether, the triangular flaps 9 arebrought over the ends of the sidestrip 2 and a. clench button or suitable fastener passed through theeyelets 10 and 11. The bottom14 is secured to the rear cross bar asshown in Fig. IV. The structure is now ready to receive the springs 13and they are placed within the recess or chamber formed by the top 1 andthe side wall portions, as shown in Fig. II. The bottom 14 is thenplaced over the springs 13 and secured to the auxiliary frame by meansof the split ring fasteners 17 which embrace the auxiliary frame. theborder wire 13 and the bottom frame and hold them together.

As I have shown inFigs. VII, and VIII, the two parts of the auxiliaryframe may be secured together by means of the right and left handthreaded coupling 18. It will also be apparent that the auxiliary framemay be of any shape depending upon the shape of the seat, and that theessence of my invention consists in the provision of an auxiliary framein two parts which may be detached from each other so that the seat maybe turned wrong side out as shown in Fig. III to enable the sewingthereon to be done on a sewlng machine. In Fig. VII I have shown awhichthe bottom 14 is omitted.

I am aware that the particular. embodiment which I have here set forthis susceptible of considerable variation without departing from thespirit of my invention and, therefore, I do not wish to be restricted tothe same. However, I have found this to be the preferred form and,therefore, I desire structure in to claim the same specifically as wellasbroadlyas indicated by my appended claims.
